Don't know how to fix AttributeError: 'function' object has no attribute 'pk' when trying to create new users from registration form

Hi, I’m still very new to Python and Django. I am trying to create a working registration page and i get this error when submitting the form. I can’t find this error when looking on stack overflow or the forum and don’t know how to fix this issue. I copied the views and models code here. Any help is appreciated

views.py

from django.shortcuts import render, redirect
from django.contrib.auth import login as authlogin, logout, authenticate
from .forms import RegistrationForm

# Create your views here.
def login(request):
    return render(request, "registration/login.html")

def signup(request):
    if request.method == "POST":
        form = RegistrationForm(request.POST)
        if form.is_valid():
            user = form.save
            authlogin(request, user)
            return redirect("/meaiapp/dashboard")
    else:
        form = RegistrationForm()
    return render(request, "registration/signup.html", {"form": form})

models.py

from django.db import models
from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin, UserManager
from django.utils import timezone


# Create your models here.
class CustomUserManager(UserManager):
    def _create_user(self, email, password, **extra_fields):
        if not email:
            raise ValueError("You have not provided a valid e-mail address")

        email = self.normalize_email(email)
        user = self.model(email=email, **extra_fields)
        user.set_password(password)
        user.save(using=self.db)

        return user

    def create_user(self, email=None, password=None, **extra_fields):
        extra_fields.setdefault("is_staff", False)
        extra_fields.setdefault("is_superuser", False)

        return self._create_user(email, password, **extra_fields)

    def create_superuser(self, email=None, password=None, **extra_fields):
        extra_fields.setdefault("is_staff", True)
        extra_fields.setdefault("is_superuser", True)

        return self._create_user(email, password, **extra_fields)

class UserProfile(AbstractBaseUser, PermissionsMixin):
    email = models.EmailField(blank=True, default="", unique=True)
    first_name = models.CharField(max_length=40, blank=True, default="")
    last_name = models.CharField(max_length=40, blank=True, default="")

    is_active = models.BooleanField(default=True)
    is_superuser = models.BooleanField(default=False)
    is_staff = models.BooleanField(default=False)

    date_joined = models.DateTimeField(default=timezone.now)

    objects = CustomUserManager()

    USERNAME_FIELD = "email"
    EMAIL_FIELD = "email"
    REQUIRED_FIELDS = ["first_name", "last_name"]

    class Meta:
        verbose_name = "User"
        verbose_name_plural = "Users"

    def get_full_name(self):
        return self.first_name + " " + self.last_name

    def get_short_name(self):
        return self.first_name```

It helps if you post the complete error message with the traceback.

Ok i took a screenshot, here is the full error message

The issue is here. This should be user=form.save()

It works now thank you so much!
